Most stereo systems have some kind of music level indicator, The indicator may be as sim pie as a set of LEDs, ordinary low-voltage lamps or V-U (volume-unit) meters. These were later replaced by bar-graph type LED indicators. Though attractive, they provide only one-dimensional ‘movement’ of LEDs with the music. Now this system has also become very common.

Presented here is a spectacular system to replace the outdated music level indicators. This system is capable of providing a smart, two-dimensional ‘dancing’ effect on a square matrix of 100 LEDs.

An endless variety of stereo amplifiers arc available in the market. But the prices of good quality amplifiers, equipped with graphic equalisers etc, are not within the reach of all audio enthusiasts. The cheaper varieties are generally based on discrete transistors, and suffer from drawbacks such as uncontrolled hum, ineffective tone controls, poor bass response, thermal runaway etc. The use of interstage transformers in such circuits reduces their versatility.

This article describes the functional and constructional details of a compact and complete solid-state stereo amplifier module, which is capable of providing an output of over 8 watts into each channel.

During the three months of work in the underpass near the cinema "Stereo" completely replaced wiring, made lining the walls and floor granite tiles, updated drainage system.

Pleased that in the finishing move on the walls and on the floor only natural materials. In the project proposal Ltd. "AvtodorProekt" Wall planned oblitsevat metal panels with tamper-resistant coating such as "Kraspan."

The three-dimensional display, capable to adapt to the user, the Laboratory developed ultrafast optoelectronics and information processing LPI together with engineers Samsung Electronics Research Center in Moscow. Basic (they breakthrough) benefits of development — "naturally" shaped volume image for each user, the maximum possible for this technology alignment settings of focus and angle of convergence of the optical axes on the subject and the high efficiency of the system.

Couple studying Sun probes STEREO mission becomes not a normal area of space. Here they will be able to search for the remains of a hypothetical ancient world, which was the nearest neighbor of the Earth. If this is proved, it is almost certain it will be possible to answer the question of where we have the moon.

"The planet called Theia — says one of the STEREO mission, working with scientists Mike Kaiser (Mike Kaiser), — this hypothesis, we have never seen a credible trace of her, although many researchers believe it existed 4.5 billion years ago and, Faced

Site "Surviving in the city" welcomes you. If you have, then you want to get complete information about survival in the modern world, in dangerous and emergency situations. People in the world today is surrounded by a large number of hazards, and therefore seeks to preserve and protect yourself from them - fires, floods, epidemics, traffic accidents, as well as the people themselves.

Site structure "Surviving in the city" built in a convenient and understandable form. All information is placed in the appropriate sections. You will find on our website recommendations and practical advice for survival in today's urban jungle, unique descriptions and photographs of incidents, accidents and natural disasters, in the scheme of the emergency situation, tests and reviews of equipment and protective equipment, useful books on survival in an urban setting.

Main theme of the site "Surviving in the city" - is to be ready to navigate and operate in extreme conditions, and the ability to survive in extreme conditions.

Surviving in an urban setting and the modern world. How to deal with the police, what to do if you are taken hostage. Survival in in other cities, survival in the army, in emergency situations. Natural disasters and man-made disasters. For the future of humanity.
